France dominated in the show jumping arena at these inaugural FEI World Equestrian Games™ in Stockholm, where Eric Navet claimed the individual honours and joined team-mates Hubert Bourdy, Roger-Yves Bost and Pierre Durand to take the team title.
Navet realised the dreams for many generations of his family when he was victorious with the stallion Quito de Baussy, bred by his father Alain at the Haras de Baussy in Calvados, Normandy. This was particularly significant given that the change-horse individual final included some of the greatest equine legends of all time including the duo of magnificent greys, Milton and Gem Twist. Silver medallists at the Seoul Olympic Games in 1988, Best and Gem Twist, knocked a rail but Gem Twist earned the title of "World's Best Horse" that afternoon when his only other mistake was with Bourdy.
It was Great Britain's Whitaker who lined up in silver medal position ahead of Bourdy in bronze while Best finished individually fourth as did the US team which also included Joan Scharffenberger (Victor), Anne Kursinski (Starman) and Joe Fargis (Mill Pearl).
The course designer in Stockholm was Olaf Petersen, whose flair and innovation had already made a big impression in Seoul. The Stockholm track had a distinctly Swedish theme.
A total of 16 countries competed in the team competition. Despite a 16-fault result for Roger-Yves Bost (Norton de Rhuys), the French were victorious in the team event, ahead of France and Germany.
The seventh FEI World Championships were held in the framework of the first FEI World Equestrian Games™ in the Olympic stadium of 1912 and 1956. Nicole Uphoff and Rembrandt, who had burst onto the international scene with their 1988 Olympic gold medal, also claimed the world title. A record number of 68 starters from 22 countries took part. The Germans won their sixth world title, with the Soviet Union (just before its break-up) and Switzerland behind on the podium.
Eighty-four riders started in Stockholm and 60 finished the competition, held in the Royal parks of Gardet and Djurgarden. Blyth Tait on Messiah earned the first individual Eventing world title for New Zealand, and Andrew Nicholson, Andrew Scott and the double Olympic champion of 1984 and 1988, Mark Todd of New Zealand, also won team gold, ahead of Great Britain and Germany.
Fifty-two starters competed from 18 countries at the first FEI World Equestrian Games™ in Stockholm, a glorious event on the whole but in terms of the Driving, they unfortunately ended with the disqualification of the winner, Ad Aarts of the Netherlands, due to traces of prohibited substances found after testing. This cost Aarts not only his individual medal but also team gold for the Netherlands. Gold instead went to Sweden. The Netherlands, with only the two scores of Chardon and Weusthof, got silver, with Hungary taking bronze. Tomas Eriksson of Sweden became the new individual World champion.
The third endurance FEI World championships were held in the framework of the first FEI World Equestrian Games™. Becky Hart of the United States with R.O. Grand Sultan won again. The surprise was the win of Great Britain in the team competition: four elderly ladies with their pet horses had the best aggregate time to take gold.
The Swiss were the winners of the first World Vaulting championship occurring as part of the FEI World Equestrian Games™ in 1990. They had had a fierce rivalry with the then-Federal Republic of Germany for over 20 years but that year the vaulters from St. Gallen were victorious. Silke Bernhard of the FRG led the women’s medals table while her countryman Michael Lehner topped the men’s table.
